The history of mobile communications parallels the history of NTT DOCOMO. Established in 1992, DOCOMO launched its first digital cellular phone service the next year and the world's first mobile Internet-services platform in 1999. It helped to establish the W-CDMA standard for mobile communications and then kick off the first 3G service based on this standard in 2001. The company also introduced one of the earliest commercial LTE services in 2010. Over the years DOCOMO has built up one of the globe's largest mobile subscriber bases, accounting for over half of the Japanese market.
